METAL WHEEL-HUB.

SPECIFICATION forming part of Letters Patent No. 719. dated January 27, 1903- Application filed July 10, 1902. Serial No. 115,070. (No model.)-

(0M whom it may concern:

Be it known that I, EDWARD R. WAGNER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Metal Wheel-Hubs, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates particularly to the construction of the flanges for attaching the spokes to the hubs.

The main object of the invention is to produce from sheet metal hub-flanges of a design that will afford firm effective fastenings for wire spokes, that will be neat and attractive in appearance, and that may be conveniently and economically made by simple stamping operations.

It consists in certain novel features of construction and in the arrangement and combinations of parts hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure l is an enlarged view of a metal wheel-hub to which myimproved flanges are applied, the flanges and one end of the hubbarrel being shown in section in planes indicated by the lines 1 1, Fig. 2. Fig. 2 is an inside elevation of one of the flanges, parts of which are broken away, the hub-barrel being shown in cross-section; and Figs. 3, at, 5, and. 6 are detail views of the component parts of asingle flange, Figs. 3 and 4: being an axial section, and Fig. 3am inside view, of the notched disk, Fig. 5 an outside View, and Fig. 6 an axial section, of the washer.

Referring to Figs. 1 and 2, CH8 the hub-barrel, which consists of a straight metallic tube, which may be conveniently made from sheet metal or seamless tubing and is formed near the ends with external shoulders or protuberances b to hold the flanges in place thereon.

Each of the hub-flanges consists of a notched disk 0 and a washer d, which are formed by simple stamping operations from sheet metal. The notched disk 0 has a central opening, in which the hub-barrel a is inserted. It is formed with an annular rim 6, bent axially outward concentric with said central opening, and from this rim the notched periphery of the disk is bent axially inward toward the center of the hub barrel. Between the notches through which the spokes f pass radially outward from the hub-barrel the projecting portions or ears 9 of the disk are primarily bent, as shown in Fig. 3, substantially parallel with the axis of the hub-barrel. When the parts of the hub with the spokesfare assembled, as shown in Fig. 1, these ears 9 are bent radially inward and clasped over the washers (1, thereby firmly binding the parts of the flange together with the spokes f between them. The washers d are formed with central flanged openings, in which the ends of the barrel a are inserted, the protuberance Z) engaging said Washers, as shown in Fig. 1, and determining the position of the flange on said barrel. From its central flanged opening the washer d is made plain or flat. The flange h around its central opening is preferably bent outward to meet or nearly meet the notched disk 0 and to afiord a wide bearingface for the attachment of the flange to the barrel a.

The outwardly-projecting annular rim 6 constitutes a sand guard or band which overhangs the end of the barrel a and gives a more finished and pleasing appearance to the hub.

My improved hub-flanges are designed for use in connection with so-called return-bend wire spokes -that is,spokes which are joined in pairs at their inner ends by continuous bends or loops, as clearly shown in Fig. 2.

Modifications may be madein minor details of form and construction within the spirit and intended scope of the invention.

I claim- 1 Ahub-flange consisting of a notched disk having a central opening and an outwardlybent annular rim concentric with said openin g, and a washer having a corresponding central opening, the projecting portions or cars of said disk being clasped inwardly over said washer, substantially as described.

2. Ahub-flangeconsistingof anotcheddisk having a central opening fitting the hub-barrel, and an outwardly-bent annular rim concentric with said opening and constituting an overhanging guard, and a washer having a central flanged opening fitting the hub-barrel, the ears between the notches in said disk being clasped inwardly over said washer, sub stantially as described.

3. In a metal wheel-hub the combination with a tubular barrel having protuberances near its ends and return-bend Wire spokes, of sheet-metal flanges each consisting of a disk having a central opening fitting over said barrel and an outwardly-bent annular rim concentric with said opening and overhanging the end of the barrel, and a fiat washer having an outwardly-flanged central opening fitting over said barrel against one or more of the protuberances near its end, the ears between the notches in the periphery of said disk being clasped inwardly over said washer and binding the parts of the flange together with the spokes between them, substantially as described.

4. In a metal wheel-hub the combination with a tubular barrel and return-bend wire spokes, of sheet-metal flanges each consisting of a disk having a central opening fitting over said barrel and a laterally-bent notched rim through which said spokes pass, and a washer having a central opening fitting over said barrel, the projecting portions or ears of said notched rim being clasped inwardly over said washer and binding the parts of the flange together and the bends of the spokes being clasped and firmly held between the disk and washer, substantially as described.

In witness whereof I hereto affix my signature in presence of two witnesses.

EDWARD R. WAGNER.
